Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material processing apparatus which prints and exposes an image on a negative film onto a photosensitive material, and is suitable for an apparatus such as a printer processor.

[0002]

2. Description of the Related Art Among photosensitive material processing apparatuses, for example, a printer processor is called a so-called minilab and is installed in a DPE store or the like. This printer processor has a printer unit that prints and exposes an image recorded on a negative film on photographic paper and a processor unit that develops the photographic paper that has been printed and exposed. Only by setting it in the printer processor, it is possible to automatically convey and process the inside of the printer unit and the processor unit. In the printer section of this printer processor, the image of the negative film is enlarged to a predetermined size selected and printed on the printing paper, and the printing paper on which the image of the negative film is printed is continuously processed by the processor. It is transported to the department, developed, and finished as a photographic print.

That is, in this type of printer processor, a long photographic printing paper is wound into a roll and housed in a magazine whose inside is shielded from light, and every time printing and exposure is performed in the printer section. It is used by sequentially pulling it from the magazine. Then, the photographic paper drawn out from the magazine by a predetermined size is printed and exposed on the exposure stage in the printer section while being nipped and conveyed by a conveyance roller and the like, and further subjected to a developing process, a bleach-fixing process and a washing process in the processor section. After that, it will be dried.

[0004]

By the way, when the photographic printing paper is initially fed into the exposure stage of the printer processor for printing exposure, if the printing paper is fed as it is, the front end of the printing paper is guttered into the opening for exposure. It enters in a curved shape, and the leading edge of the photographic paper hits the edge of the opening.

Therefore, it is necessary to close the opening so as not to hit the edge of the opening at the initial feeding of the printing paper. For this reason, for example,
As disclosed in Japanese Patent No. 38, No. 38, it has been considered to insert a loading blind plate so as to cover the opening or attach an opening / closing lid to the exposure stage itself.

However, if a blind plate for loading is used,
It has a drawback that the loading blind plate needs to be attached and detached for each initial feeding operation of the printing paper, which complicates the operation. Further, when the opening / closing lid is simply attached to the exposure stage, not only the opening / closing lid needs to be opened / closed, but also the exposure stage has to be enlarged by the amount of movement of the opening / closing lid. It was

On the other hand, a paper mask is required for fixing the printing paper at the time of printing exposure, and when the paper mask is loaded at a predetermined position in the exposure stage, the printing paper is conveyed along with the insertion of the paper mask. There was a need to shift the printing paper out of the paper mask entry path.

For this reason, conventionally, it is known that a guide member for retracting the photographic paper is provided in association with the insertion of the paper mask when the paper mask is loaded, but conventionally, the mechanism is complicated. Had.

Further, in recent printer processors,
For example, a sub-exposure unit for character printing has come to be installed inside or outside the exposure stage so that characters such as "graduation anniversary" can be printed on a photographic paper together with a negative film image. .

However, when a main exposure part for printing and exposing an image on a negative film and a sub-exposure part for printing and exposing an image different from the exposure light from the negative film are provided, the image can be printed properly at each position. , The photographic paper must be properly pressed against the paper mask at each position, but even if the pressing plate for pressing is simply enlarged, it is difficult to press the photographic paper uniformly and the printing exposure cannot be performed properly. Had.

In consideration of the above facts, the present invention facilitates the initial feeding of the printing paper into the exposure stage and the loading of the paper mask into the exposure stage, and stabilizes the printing exposure in the exposure stage. It is an object to obtain the intended photosensitive material processing apparatus.
